Couplers - Excavator

Quick Couplers are the high-performance option for Cat® Excavators. Couplers allow one man to change work tools in seconds for maximum performance and flexibility on the job site. One machine can move rapidly from task to task, and a fleet of similarly equipped machines can share a common work tool inventory.
